Abstract (en)
[origin: WO2018224100A1] The invention relates to a hollow needle for an ophthalmic instrument for in-vivo fragmentation and removal of organic lenses by means of ultrasound, having a connection region (2) formed on the proximal end (1) for connecting to the instrument, and a needle tip (4) formed on the distal end (3) having at least one effective surface (5) for fragmenting the lens material, wherein, in the axial direction, a suctioning channel (6) for suctioning off lens fragments extends through the hollow needle, the at least one opening (7) of which suctioning channel is bounded by an effective surface (5). The invention is characterised in that the distal end (3) of the needle tip (4) is closed and the at least one effective surface (5) is arranged laterally close to the needle tip (4), wherein the closed needle tip (4) has a cutting surface for cutting the lens.
